Guan Yuan ascended the stairs and saw Su Mo inspecting in front of the door, so she also glanced behind the door.

She immediately spotted an obvious massive hole in the back section’s center of the corridor on the second floor.

The edges of the hole were disorganized and jagged, with visible traces of force used to create it.

“I suppose the mutant rat must have gone down from there.”

Su Mo wore a surprised expression.

‘The time it took for the rat to show up was extremely long and it showed zero flexibility to dodge the bullets shot at it.

‘It wasn’t originally on the first floor but was locked on the second floor.

‘He forcefully made a hole in the floor to get down and charged at the door to attack the sudden intruders after falling through the hole.

“It definitely had no intelligence.

“Smashing this door would be much easier than breaking the floor!”

Su Mo leaned into the door and began to fiddle with it as he sarcastically joked about the rat.

The large lock on the door was highly troublesome at a glance. However, the structure of the lock was not even comparable to a Grade C padlock.

It was not necessary to get a professional locksmith, and even an unqualified individual could easily unlock it by hitting it a few times.

Su Mo took out a thin iron wire on him and easily picked open the lock.

Bang…

Su Mo opened the padlock and threw it aside. The door was no longer bounded and gradually swung open by the wind, revealing the interior of the second floor.

“One, two, three… There are five rooms on the second floor.” Su Mo walked toward the first room on the right as he muttered to himself.

The room was also covered in thick layers of dust like the outside, and not a single area was spared from it.

The furnishing inside was even simpler. It had two desks, a bedside table, and a large bed without bedsheets.

Su Mo scanned the room and tried to extract as much information as possible from the room that could prove the origin of the building.

His gaze swept across the edge of the bed, and a yellow piece of paper stuck between the bed’s seam.

“This is..”

The exposed part of the paper seemed highly familiar, but he could immediately recall it.

A suspicion immediately came to his mind. He approached the bed, pushed away the mattress, and then carefully picked up the paper.

Paper processed by humans can be preserved for several years without decaying in an environment exposed to the sun and rain.

It had no problem surviving in a closed-off room.

Su Mo swept away the dust on it, revealing the words and pictures written on it.

“…”

The dense words printed on the A4 size paper would surprise anyone who had read it.

The meaning represented by the words was not as simple as it looked.

“Oh? It’s Mazu Shelter No. 3. They’re located near the coast and have a lot of supplies. Initially…”

Guan Yuan approached Su Mo and saw the flyer’s title, then began to excitedly blabber.

Seconds later, she realized Su Mo’s severe expression and immediately came to her senses.

Since the flyer found in the house belonged to their hometown, the house’s origin was…

“It’s from our Earth!”
